In this case, you live a meaningful life, living a happy life (Rubin). Helping an elderly person cross the street brings happiness to oneself, and when others see that act of kindness, they want to help others too; it's like a chain reaction (Esfahani). One helps others who lives a meaningful life and feels good about himself, which means living a happy life. However, too many sacrifices in an attempt to live a meaningful life can be detrimental to one's happy life. We need to find the perfect balance between too much sacrifice and too little sacrifice.

You create an impact on the world and, at the same time, you find happiness: everyone's desire. No child wants that
